Specification of Letters Patent.

atented Aug. 25, 1914.

Application filed May 19. 1913. Serial No. 768.588.

To all whom. it may concern lie it known that I. \ViLLL-nr lVooouuno, a citizen of the United States and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain nevi and useful Improvements in lllxplosive-llngines, of which the following is a specification.

My invention relates to improvements in explosive engines and especially to valves therefor and means for operating the same, the objectof the lllVtIltlLlil being: to provide an in'iproved form of valve for such engines and improved means for operating the same.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a vertical section. partially in elevation, of an explosive engine embodying my invention, Fig. 1'), a section taken on line zc-w of Fig. l. and Fig. 8 is a section taken on line g g of Fig. 2.

The preferred form of construction as illustrated in the drawings comprises a cylinder 1 having separate semicylindrical sleeve sections 2 and 3 reciprocating therein. A piston at is arranged to reciprocate within sleeves 2 and 3 and is connected bymeans of a coi'mecting rod 5 with the crank pin 6 of an ordinary crank shaft 7 mounted in crank case 8 in any suitable or desired manner. A cam shaft 9 is also arranged in crank shaft 8 and is geared to run at one-half of the speed of crank shaft 7, the engine illustrated being of the ordinary :lmir-cycle type. Cam shaft 9 carries eccentric 10 and it which are set thereon as shown and engage forks 1:2 and 13 respectively formed at the ends respectively of rock levers l-land 15 as shown. spectively with sleeve sections 2 and. 3 by means of links in and 1?. so that said sleeve sections will be recipiwicated independently of each other by means of eccentrics 1.0 and 1.1 as will be readily understood by those skilled in the art. Supplemental valve cylii'iders 18 and 19 are forn'icd at the head of cylinder 1 and'in open comn'iunication therewith, cylinder 18 being provided with an exhaust port "20 and cylinder 19 being provided with an intake port .21 as will be,

readily understood. Spring ring valves 22 Levers it and l5 are connected re-- and are arranged to reciprocate in c vlinders 18 and 19 respectively and open and close ports 20 and 21 therein. These sprii'ig ring valves 22 and 23' are connected respec: tively with tongues 2-1 and 95 projecting upwardly from the ends of sleeves 2 and 3 respectively, and eccentrics 10 and 11 are so positioned on cam shaft 9 as to move sleeve sections and 3 in proper relation to open and close said ports at the proper times as will be readily understood by those skilled in the art. For convenieimc in manufacture the upper ends of chambers 18 and it) are closed by threaded plugs 26 and 27 and a suitable spark plug 28 is arranged in the head of cylinder 1 as will be readily understood. The form of valve disclosed constitutes a simple and effective one for the purpose and will be found to be highly eflicient in use.

\Vhile I have illustrated and described the preferred 01 in of construction for carrying my invention into effect this is capable of 'ariation and modification without departing from the spirit of the invention. 1, therefore, do not Wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications a come within the scope of the appended claims.

Having described my invention What I claim as new and desire to secure by Letters Patent is:

1. An explosive engine comprising a crank use: a main cylinder secured at one end to said crank case; two valve cylinders arranged at the other end of said main cylinder in open communication therewith, said. valve cylinders being provided with ports; a reci 'n'ocating valve in each of said valve cylinders. each of said valves being an annular member of resilient material split longitudinally thereof: a pair of sleeves in said main cylinder: an operative connection between each of said valves and one of said sleeves: a piston within said sleeves; a c ank shaft in said crank case: and means in said crank case operatively connected with said crank shaft and arranged to operate said sleeves and valves, substantially as described.

An explosive engine comprising a main cylinder, a piston and cooperating parts; valve chan'ibers independent of said main cylinder, in open communication therewith and provided with suitable ports; valves in said valve chamber, each of said valves being i an annular member of resilient material split longitudiimlly thereof: a crank shaft; and operative connections for said valves with said crank shaft passing through said main cylinder, substantially as described.

3. An explosive engine comprising a main 7 cylinder, a piston and cooperating parts; independent reciprocating sleeve sections in said cylinder, each of said valves being an annular member of resilient material split longitudinall thereof; two valve chambers 1 arranged at the head of said cylinder in open communication therewith, there being; an exhaust port in one of said chambers and an admission port in the other; a valve in; each of said chambers; a tongue on each of said sleeve sections engaging one of said valves; and means for reciprocating said sleeve sections to control said valves aud= ports, substantially as described.

t, An explosive engine comprising a main cylinder, a piston and cooperating parts; independently reciprocating sleeve sections in said cylinder surrounding'said piston; two cylindrical valve chambers arranged at the head of said cylinder and in open communication therewith, there being an exhaust port i 1 i i I i l t l l l l i i l 1 in one oi said chambers and an admission port in the other; a. valve in each 01. said chambers; a tongue on each of said sleeve ;.cctions engaging one of said valves; and means for reciprocating said sleeve sections to control said valves and ports, substantially as described.

5. An explosive engine comprising a main cylinder, a piston and cooperating parts; imlepeiulently reciprocating sleeve sections in said cylinder surrounding said piston; tvvo cylindrical valve chambers arranged at 40 the head of said cylinder and in open com munication therewith, there being an evhaust port in one of said chambers and an admission portin the other; a spring ring valve in each of said chambers; a tongue 01145 each of saidsleeve sections engaging one of: said valves: and means for reciprocating said sleeve sections to control said valves and ports. sul'isti-antially as described.

lu testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
